Application filed September 16, 1920. I Serial No. 410,601.

To all whom it may concern:

. formed Wit Be it known that I, FRANK Monnswoirrrr, of 10 King Street,Arch Hill, Auckland, in the Provincial District of Auckland, in theDominion of New Zealand, a subject of the King of- Great Britain andIreland, have invented certain new and useful Improvements in anImproved Nail for Packing Cases and the like, of which the following-.the entrance of the nail into the wood,

is a specification.

This invention provides an lmproved nail especially adapted for use as afastening in the construction and securing of packing,

cases and the like from which it is desired to prevent pilfering,

Accordin a solid lower portion, the remaining portion being hollow. i

A head is provided around the upper end of the hollow portion and thelower portion besides being pointed to facilitate the entrance of thenail into the wood, is also: pro ects uppointed at its upperend which:wards into said hollow portion.

-A. member splitinto legs is housed in the hollow portion, the latterbein vided with side opening level wit the pointed upper end of thesolid portion. The legsof the split member are sharp ened on the innersidesof their lower ends wards in the hollow portion, after the nail hasbeen driven into the wood, said legs comin are so arated and spreadoutwards through the side openings in the hollow portion, by incontactwith the pointed upper end 0 the solid portion and enter the wood,thereby providing anchoring means, which prevents said nail from beingwithdrawn or the board "secured thereby from being removed, except bysplitting or otherwise damaging the wood. The invention will'be moreparticularly described in conjunction with'the accompanying drawing, inwhich:-'

Figure 1 is an enlarged sectional elevation of a portion of a caseshowing a nail secured therein.

Figure 2 is a part sectional elevation of the'same nail on a largerscale, but be- .fore the split member-isptorced downwards to theinvention, the nail is pro.

Figure 6 is an elevation of a nail in which the hollow and solidportions are integral and showing the legs of the split member emergingfrom the hollow portion.

In the. drawing, 1 is the'solid lower portion of the nail and 2 thehollow portion i the latter being provided with a .head 3 around tsupper end and the former besides being pointed in order to facilitatehaving a concave conical upper-end 4 which pro ects upwards into thehollow ortion 2. The member 5 housed within t e hollow portion 2, issplit for the greater part of its length into legs'fi, each of which issharpened atthe inner side of its lower en cave conical end 4 of theportion 1.

The solid portion 1 can be screwed into the hollow portion 2 and be.provided with a shoulder or shoulders 8 for the lower end of the portion2 to bear against, as in Figiures 1 and 2, or it can have a groove orportion 1 being of a concave conical formation, a concave knife edge end4 can be I 90 When nailing two pieces of wood together,

provided as shown in Figures 4 and 5.

For eathleg 6, a side opening 7 is provided 1n the portion 2 level withthe'consay for instance the end of a lid 10 to a .case end 11, themember '5 is completely housed in the hollow portion 2, with the lowerends of the le s 6 resting on the pointed upper end of t e solid portion1.

After the nail has been driven right home, the member 5' is punched orotherwise forced downwards in the hollow portion 2,

whereupon the legs -6 owing to'the shape of their lower ends and to thepointed upper end of the solidportion 1, are caused to separateandspread outwards through the openings 7 v and bury themselves in the caseen 1 The shape of the ends of said legs also causes-same to take anupward path through 4 the. wood with the result that the nail becomessecurely anchored in the case end 11 as shown.

. i I The nail cannot be withdrawn and the {board orthe like it securescannot be re,

moved except by splitting the wood, or leaving other tell tale evidenceof pilfering.

Having now particularly descnbed and ascertained the nature of thisinvention and in what manner the same is to be performed I deolare thatwhat I claim is A non-removable nail comprising a hollow tubular memberhaving a head at its upper end and a pair of dlametricallyopposite holesat its lower end; a solid pierc- 1 ing member separate from said hollowmember and reduced at its upper end to fit and be secured to the hollowmember, said re duced portion of the solid piercing member having a pairof cam surfaces one for each hole, said piercing member having asharpened point at its othervend; and an anchoring member mounted withinsaid FRANK MOLESWORTH.
